JSON in Java [package org.json]JSON is a light-weight, language independent, data interchange format.Seehttp://www.JSON.org/The files in this package implement JSON encoders/decoders in Java.It also includes the capability to convert between JSON and XML, HTTPheaders, Cookies, and CDL.This is a reference implementation. There is a large number of JSON packagesin Java. Perhaps someday the Java community will standardize on one. Untilthen, choose carefully.The license includes this restriction: "The software shall be used for good,not evil." If your conscience cannot live with that, then choose a differentpackage.The package compiles on Java 1.6-1.8.JSONObject.java: The JSONObject can parse text from a String or a JSONTokenerto produce a map-like object. The object provides methods for manipulating itscontents, and for producing a JSON compliant object serialization.JSONArray.java: The JSONArray can parse text from a String or a JSONTokenerto produce a vector-like object. The object provides methods for manipulatingits contents, and for producing a JSON compliant array serialization.JSONTokener.java: The JSONTokener breaks a text into a sequence of individualtokens. It can be constructed from a String, Reader, or InputStream.JSONException.java: The JSONException is the standard exception type thrownby this package.JSONPointer.java: Implementation of [JSON Pointer (RFC 6901)](https://tools.ietf.org/html/rfc6901). SupportsJSON Pointers both in the form of string representation and URI fragmentrepresentation.JSONString.java: The JSONString interface requires a toJSONString method,allowing an object to provide its own serialization.JSONStringer.java: The JSONStringer provides a convenient facility forbuilding JSON strings.JSONWriter.java: The JSONWriter provides a convenient facility for buildingJSON text through a writer.CDL.java: CDL provides support for converting between JSON and commadelimited lists.Cookie.java: Cookie provides support for converting between JSON and cookies.CookieList.java: CookieList provides support for converting between JSON andcookie lists.HTTP.java: HTTP provides support for converting between JSON and HTTP headers.HTTPTokener.java: HTTPTokener extends JSONTokener for parsing HTTP headers.XML.java: XML provides support for converting between JSON and XML.JSONML.java: JSONML provides support for converting between JSONML and XML.XMLTokener.java: XMLTokener extends JSONTokener for parsing XML text.Unit tests are maintained in a separate project. Contributing developers can test JSON-java pull requests with the code in this project:https://github.com/stleary/JSON-Java-unit-testNumeric types in this package comply with ECMA-404: The JSON Data Interchange Format (http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-404.pdf) and RFC 7159: The JavaScript Object Notation (JSON) Data Interchange Format (https://tools.ietf.org/html/rfc7159#section-6). This package fully supports Integer, Long, and Double Java types. Partial support for BigInteger and BigDecimal values in JSONObject and JSONArray objects is provided in the form of get(), opt(), and put() API methods.Although 1.6 compatibility is currently supported, it is not a project goal and may beremoved in some future release.In compliance with RFC7159 page 10 section 9, the parser is more lax with what is validJSON than the Generator. For Example, the tab character (U+0009) is allowed when readingJSON Text strings, but when output by the Generator, tab is properly converted to \t inthe string. Other instances may occur where reading invalid JSON text does not cause anerror to be generated. Malformed JSON Texts such as missing end " (quote) on strings orinvalid number formats (1.2e6.3) will cause errors as such documents can not be read reliably.Release history:20171018    Checkpoint for recent commits.20170516    Roll up recent commits.20160810    Revert code that was breaking opt*() methods.20160807    This release contains a bug in the JSONObject.opt*() and JSONArray.opt*() methods, it is not recommended for use.Java 1.6 compatability fixed, JSONArray.toList() and JSONObject.toMap(),RFC4180 compatibility, JSONPointer, some exception fixes, optional XML type conversion.
